Best soundproofing?


Nov 17, 2012

I'm building a PC for the first time and was thinking about soundproofing it a bit. I'm using the "Antec One Black Midi Tower Gaming Case".

Any advice?
Best thing to do is keep the power consumption down so the fans dont have to work hard. Sound proofing foam is ok but put it in an overclocked gaming system and you will just cook it. Just keep the power consumption low and buy some decent fans and maybe a fan controller.

You're right, but the reason I want to soundproof it is because I have read online that the graphics card I've ordered is very loud. Could I just use a bit of sound proofing foam to reduce noise, without over heating? Where can I buy sound proofing foam for PCs?

So far I've ordered the following:

Asus P8Z68-V PRO/GEN3 Motherboard

XFX ATI Radeon HD 6870 Graphics Card

Antec One Midi Tower Case

16GB kit (8GBx2), 240-pin DIMM, DDR3 PC3-12800 memory module

LG BH10LS38.AUAR 10x Internal BD-RW

Western Digital Caviar 3TB SATA 6 GB/s 64MB Cache 3.5 inch OEM Internal Hard Drive Green

And I'm planing on ordering the following (come pay-day):

ASUS Xonar D2X/XDT - Sound card OR Asustek Xonar DX/XD PCI-E Low Profile Sound Card

Cooler Master Hyper 212 EVO

Intel Sandybridge i5-2500K Unlocked Core i5 Quad-Core Processor (3.30GHz, 6MB Cache)

A PSU (I'm not 100% which one I want to get yet), some thermal compound and maybe 2 or 3 more fans.

I don't think it would be a good idea for that build, I think it will just overheat. My build gets very hot and I have a big overkill CPU cooler with a similar GPU (in power consumption terms)

I had the same problem, my GPU was quite noisy so I took the shroud off it and cable tied a Noctua NF-P12 fan to it. My PC is really quiet now and the idle temps are actually lower. I just used that one because it was lying around, if I bought a fan I would definitely get a PWM one, or maybe 2 x 80mm PWM ones. You would need one of these adapters to do that:

One of these too if you use two fans.
Noise comes from fans running at high rpm's.
There is not much you can do about the fan on the graphics card, except perhaps underclocking the card.
The newer 28nm cards(GTX6xx and amd 7xxx) cards take less power and are quieter.

Try to use slow turning fans, and as few of them as possible.
I would try just the stock fans that come with the case. They should be adequate, and have, I think , a two position speed switch.

The stock intel cooler has a small 92mm fan that gets loud under load.
Something like a cm hyper212 is not expensive, and the 120mm fan will cool better and be quieter.
The hyper212 cooler is 160mm tall, and will fit if you do not install an optional side fan in the case.

If you want to experiment with sound deadening foam, Silverstone silent foam SF01 is not expensive.
Ditch the discrete sound card. Onboard is very good, at least try it first.

A 6870 needs a 500w psu. If you overprovision a bit, the psu will loaf, and the fan will not add to noise.
Perhaps a 650w unit would be better.
Buy only a quality unit.
For reference look at tier 1 or 2 units from this list:

And thank you geofelt. Very useful.

I don't know of any graphics card cooler where you would not have to take the card apart to install.
It is not that difficult to do, but the results may not be ad great as you might think.
Replacing with a liquid cooler block will still need a radiator somewhere else, and that will still need a fan that generates noise.

I think it best to see how you do with what you bought before making any changes.
By the time you spend money on fancier coolers, you would be better advised to sell/return the card for a stronger/quieter card in the first place.
I have never heard of a fan cooled GPU that is inaudible when idling though, if you're going for something seriously quiet then I'm not sure there are any manufacturers that make GPU's like that.

Don't get me wrong, some are very quiet but you can still hear them. That's fine for most people, I'm just a bit of a quiet freak. MSI and ASUS seem particularly good to me for quieter cards. Palit are pretty terrible for it, I had to mod my card and I've heard of other noisy ones. From what I've heard of Gigabyte, they're a bit hit and miss with it. Some are great and some are horrible.

On newegg, there are 113 fanless graphics cards.
The problem is tha they are relatively low end cards.
The strongest is probably a 7750 like this.

There are also fanless cpu coolers.
The problem is that even fanless components need some sort of airflow which must be supplied by fans.
It is possible to build a silent pc only with relatively low end parts.
But... Quiet is entirely different, and very possible, even with very good performance.
Yeah I know you can get fanless cards, which is why I said I have never heard of a fan cooled card which is inaudible when idling. You could easily do that if you were able to choose your own fan though. Most of Noctua's PWM fans go down to 300RPM, that should be inaudible regardless of the fan size. Just saying I've never heard/heard of/seen a GPU that comes with fans that quiet.

You can get a passive HD 6850 and HD 7770 as well, as far as I know they're the most powerful passive cards available.
